An apparatus for displaying a heat map on a perspective drawing uses a processor to detect objects from images captured by multiple cameras with different orientations. The processor calculates the horizontal distance between each detected object and each camera, then adjusts the object's size using this distance to generate a perspective drawing. This drawing highlights 'dead zones' (areas not covered by cameras within a particular region). An object display shows the detected objects on the perspective drawing based on their calculated horizontal distances. A heat-map display then shows a heat map according to the density of object traces on this drawing. The horizontal distance calculation specifically uses the object's height on the ground, its height in the camera image, and the camera's focal length, assuming the camera's optical axis is parallel to the ground. The cameras exchange live video signals to collaboratively generate the perspective drawing.
